Amazon introduced a new Cloud Drive service offering browser-based file storage and music streaming. In the countries where this is offered, anyone with an Amazon account can receive 5 GB of free storage.

Unfortunately, the service doesn't work with Mobile Safari. But if you use a third-party browser on your iOS device which enables you to change the User Agent setting, like Atomic Browser (US $1) or Mobile iCab (US $2), then simply set it to use desktop Safari as the User Agent and the Amazon service works fine.
